boolglStrictBindingFollowsDriver: Whether strict binding follows the driver or has been overwritten by a user defined config value. If true is set by the OpenGL Scene during initialization. If false glStrictBinding is set from a config value and not updated during scene initialization.

shapedChanged(): Signal emitted when the window's shape state changed. That is if it did not have a shape and received one or if the shape was withdrawn. Think of Chromium enabling/disabling KWin's decoration.

needsRepaint(): Emitted whenever the state changes in a way, that the Compositor should schedule a repaint of the scene.

activitiesChanged(KWin::Toplevel *toplevel)

screenChanged(): Emitted whenever the Toplevel's screen changes. This can happen either in consequence to a screen being removed/added or if the Toplevel's geometry changes. 4.11

boolactive: Whether this Client is active or not. Use Workspace::activateClient() to activate a Client. Workspace::activateClient

QStringcaption: The Caption of the Client. Read from WM_NAME property together with a suffix for hostname and shortcut. To read only the caption as provided by WM_NAME, use the getter with an additional false value.

boolcloseable: Whether the window can be closed by the user. The value is evaluated each time the getter is called. Because of that no changed signal is provided.

boolfullScreenable: Whether the Client can be set to fullScreen. The property is evaluated each time it is invoked. Because of that there is no notify signal.

boolmaximizable: Whether the Client can be maximized both horizontally and vertically. The property is evaluated each time it is invoked. Because of that there is no notify signal.

boolminimizable: Whether the Client can be minimized. The property is evaluated each time it is invoked. Because of that there is no notify signal.

boolmodal: Whether the Client represents a modal window.

boolmoveable: Whether the Client is moveable. Even if it is not moveable, it might be possible to move it to another screen. The property is evaluated each time it is invoked. Because of that there is no notify signal. moveableAcrossScreens

boolmoveableAcrossScreens: Whether the Client can be moved to another screen. The property is evaluated each time it is invoked. Because of that there is no notify signal. moveable

boolprovidesContextHelp: Whether the Client provides context help. Mostly needed by decorations to decide whether to show the help button or not.Returns whether the window provides context help or not. If it does, you should show a help menu item or a help button like '?' and call contextHelp() if this is invoked.contextHelp()

boolresizeable: Whether the Client can be resized. The property is evaluated each time it is invoked. Because of that there is no notify signal.

boolshadeable: Whether the Client can be shaded. The property is evaluated each time it is invoked. Because of that there is no notify signal.

booltransient: Whether the Client is a transient Window to another Window. transientFor

KWin::ClienttransientFor: The Client to which this Client is a transient if any.

QSizebasicUnit: By how much the window wishes to grow/shrink at least. Usually QSize(1,1). MAY BE DISOBEYED BY THE WM! It's only for information, do NOT rely on it at all. The value is evaluated each time the getter is called. Because of that no changed signal is provided.

boolmove: Whether the Client is currently being moved by the user. Notify signal is emitted when the Client starts or ends move/resize mode.

boolresize: Whether the Client is currently being resized by the user. Notify signal is emitted when the Client starts or ends move/resize mode.

boolspecialWindow: Returns whether the window is any of special windows types (desktop, dock, splash, ...), i.e. window types that usually don't have a window frame and the user does not use window management (moving, raising,...) on them. The value is evaluated each time the getter is called. Because of that no changed signal is provided.

boolwantsInput: Whether the Client can accept keyboard focus. The value is evaluated each time the getter is called. Because of that no changed signal is provided.

QPixmapicon

KWin::TabGrouptabGroup: The "Window Tabs" Group this Client belongs to.

boolisCurrentTab: Whether this Client is the currently visible Client in its Client Group (Window Tabs). For change connect to the visibleChanged signal on the Client's Group.

QSizeminSize: Minimum size as specified in WM_NORMAL_HINTS

QSizemaxSize: Maximum size as specified in WM_NORMAL_HINTS

booldecorationHasAlpha: Whether the decoration is currently using an alpha channel.

intdesktop: The desktop this Client is on. If the Client is on all desktops the property has value -1.Returns the virtual desktop within the workspace() the client window is located in, 0 if it isn't located on any special desktop (not mapped yet), or NET::OnAllDesktops. Do not use desktop() directly, use isOnDesktop() instead.

boolonAllDesktops: Whether the Client is on all desktops. That is desktop is -1.

boolfullScreen: Whether this Client is fullScreen. A Client might either be fullScreen due to the _NET_WM property or through a legacy support hack. The fullScreen state can only be changed if the Client does not use the legacy hack. To be sure whether the state changed, connect to the notify signal.

QRectgeometry: The geometry of this Client. Be aware that depending on resize mode the geometryChanged signal might be emitted at each resize step or only at the end of the resize operation.

boolkeepAbove: Whether the Client is set to be kept above other windows.

boolkeepBelow: Whether the Client is set to be kept below other windows.

boolminimized: Whether the Client is minimized.

boolskipTaskbar: Indicates that the window should not be included on a taskbar.

boolskipPager: Indicates that the window should not be included on a Pager.

boolnoBorder: Whether the window has a decoration or not. This property is not allowed to be set by applications themselves. The decision whether a window has a border or not belongs to the window manager. If this property gets abused by application developers, it will be removed again.

booldemandsAttention: Whether window state _NET_WM_STATE_DEMANDS_ATTENTION is set. This state indicates that some action in or with the window happened. For example, it may be set by the Window Manager if the window requested activation but the Window Manager refused it, or the application may set it if it finished some work. This state may be set by both the Client and the Window Manager. It should be unset by the Window Manager when it decides the window got the required attention (usually, that it got activated).

boolblocksCompositing: A client can block compositing. That is while the Client is alive and the state is set, Compositing is suspended and is resumed when there are no Clients blocking compositing any more.This is actually set by a window property, unfortunately not used by the target application group. For convenience it's exported as a property to the scripts.Use with care!

closeWindow(): Closes the window by either sending a delete_window message or using XKill.
